Introduction: Organophosphates are pesticides used for agricultural purposes, and their poisoning has critical complications. The purpose of this study was to determine the estimated Red Blood cell distribution width (RDW) prognostic role in patients with organophosphate poisoning in the emergency department. Materials and methods: In this Descriptive-analytical study, patients with acute organophosphate poisoning referred to the emergency department of Sina Hospital in Tabriz from March 2019 to March 2020 were enrolled. The primary outcome of the patients including, organophosphate-induced RDW changes, and the secondary outcome including, organophosphate-induced death were recorded. Results: Eighty two patients with organophosphate poisoning were enrolled in this study. The mean age was 36.21 years. Of 82 patients, insecticidal poisoning, herbicide, fungicides, and acaricide were seen in 62 (76.8%), 16 (19.5%), 1 (1.2%), and 1 (1.2%) patients respectively. There were no statistically significant difference observed between types of pesticides and patients’ outcomes (p> 0.05). There was no statistically significant difference between different organophosphates in terms of pH, HCO3 , PCO2 , WBC, Hb, platelets, RDW, sodium, potassium, PT, PTT, INR, urea, creatinine, and cholinesterase (p> 0.05). Conclusion: Generally, RDW in patients with organophosphates toxicity does not have prognostic value and is not affected by the severity of poisoning.

Background. Drugged driving is a growing traffic safety issue in many countries. Adequate knowledge of physicians concerning the effects of different medicines on driving can help them prescribe safer medications. This study aimed to assess the knowledge and attitudes of family physicians regarding the effect of medicines on driving. Methods. This cross-sectional study was conducted on 91 family physicians in East Azerbaijan Province. A researcher-made questionnaire was used for data collection. This study considered knowledge and attitude as dependent variables and demographic characteristics as independent variables. To investigate the relationship between independent and dependent variables, independent t-test, one-way analysis of variance (ANOVA), chi-square, and multiple linear regression were used. Data were analyzed using Stata version 17. Results. According to the results, almost 65 (71.43%) of the participants were women and 26 (28.57%) were men with an average age of 31.54 years. The average score of physicians’ attitude about the effect of medicines on driving was 71.70 ± 14.94, and the average score of their knowledge was 37.52 ± 10.23. Therefore, 44 (48.35%) of the physicians had a good level of attitude, whereas 46 (52.87%) of them had a low level of knowledge regarding medications and driving. Receiving education regarding medications and driving was significantly correlated with the level of knowledge and the attitude of physicians (P<0.05). However, no significant relationship was observed between the attitude and knowledge of physicians and other demographic variables. Conclusion. Considering physicians’ inadequate knowledge regarding the effect of medicines on driving, it is essential to hold training and retraining courses in the field of medicines and driving for physicians and develop a classification system for the drugs affecting driving in Iran. Practical Implications. The findings of this study can be presented to the policy-makers of the Ministry of Health in order to provide an opportunity to boost the knowledge and attitude of physicians regarding medicines and driving with the support of universities of medical sciences. As a result, an important step can be taken to reduce traffic accidents caused by prescription medicines.

Background and Objectives Burns is one of the most common and potentially dangerous public health problems. Burn patients' hospitalization facilitates the provision of medical services. However, prolonging the length of hospital stay can not only impose an economic cost, but also cause various infections in patients. Various factors affect patients’ hospitalization length including patients age and gender, burn cause, anatomic place and its severity. Identifying and considering these factors will reduce burn patient’s hospitalization and its consequences. The aim of this study was to evaluate the factors affecting hospitalization length in burn patients admitted to Sina Hospital as burn referral hospital in Northwest of Iran. Material and Methods In this cross-sectional study, the medical records of burn patients who were admitted to Sina Hospital in Tabriz during 2018, were included. Data collection was performed using a goal-based researcher data collection form. The form included patient’s demographics (age, gende, marital status, education level, occupation, comorbidity) and Status of vital signs at admission including respiratory rate, heart rate, body temperature, Glasgow Coma Scale score (less than 12 moderate injuries, 13 and 14 mild injuries, 15 or more normal) and systolic and diastolic blood pressure, burn place, date, cause, TBSA, burn severity, length of stay and outcome. Data were analyzed using Stata 16 software and through quantile regression modeling. Data normality was evaluated using Kolmogorov-Smirnov test, skewness and kurtosis. Due to the skewness of the hospitalization variable distribution (hospitalization length was a non-negative variable with right skew and skewness coefficient of 4.72 and kurtosis coefficient equal to 6.53), to obtain a complete picture of how the conditioned distribution of the response variable changes from variables Independently, Quantile regression was used for modeling with a significance level of P <0.05. Results The total number of hospitalized burn patients was 1586 of whom 998 (62.3%) were male. The mean age of the patients was 25.5 ± 22.9 years. Most of the patients were in age-group 0-5 years. About 22.3% of patients were in Tachypnea situation and 33.3% had low blood pressure. Based on Glasgow score, 0.3% of patients were with moderate and 2.2% with low injury. Only 15.4% of patients were with more than 20% burn in their body. Burn degree III was the most prevalent injury (35.1%). Upper limbs (62.9%) were the most anatomic sections injured in burn. Totally 94 patients (5.9%) were died due to burn injuries. Burns occurred more often in summer (30.5%) and at home (n=1246, 78.6%). The median length of hospitalization was 8 days (95% CI: 7.34-8.57). Single (P = 0.010) and illiterate patients (P = 0.022) had a longer hospitalization length. The lower the Glasgow coma score at admission, resulted in longer hospital stay (P = 0.034). Patients with burn on face (P = 0.037), head and neck (P <0.001) and back of the trunk (P = 0.031) had longer hospital stay, respectively. The higher the percentage of burns, the longer the hospital stay (P <0.001) and the presence of concurrent trauma also increased the length of hospital stay (P <0.001). Conclusion Glasgow coma score, burns on the face, neck and back were identified as effective clinical signs on hospitalization length of stay amongst burn patients. Considering these factors in the triage of burn patients, providing quality treatment and care services to manage these symptoms can reduce the length of hospital stay and ultimately lead to a reduction in social and economic costs for patients and society.
